Try asking. Back in my single days, I sent a letter to Old Spice telling them that I loved their after shave and cologne because women would instantly swoon over me as soon as they caught a whiff of that stuff. I actually didn't ask them for any freebies but they sent me a bunch of coupons for FREE Old Spice products.
Now I’m going to have to try that. Every time I want something, I’ll have to shoot off a letter first to see if I can get it for free.
